AIR-FILTERING GAS-BURNER.

Application filed. April 3, 1916.

T0 all whom it may concern:

Be it known that I, XVILLIAM B. PARKS, a citizen of the United States, residing at Fort Vorth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in riir-Filtering Gas-Burners, of which the following is a specification.

My invention relates to improvements in gas burners and more particularly to means for filtering air for use in burners for cooking and heating purposes, and the object is to provide a simple and inexpensive device for filtering the air to prevent choking of the burners and for regulating the amount of air fed to the burners or fed to the mixing chambers for mixing withthe gas prior to the feeding of the gas to the burners and to provide a simple device which can be at tached to gas burners of ordinary construction.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings in which similar characters of reference are used to indicate the same parts throughout the several views.

Figure 1 is a plan view of the improved filtering device as applied to burners of ordinary construction. Fig. 2 is a broken vertical section of the air feeding chamber, illustrating the manner of regulating the amount of air fed to the mixing chamber. Fig. 3 is a face view of the filtering air receiver. Fig. l is a similar view to Fig. 2, but showing a variation in the regulating valve. Fig. 5 is a broken horizontal section of the air feeding chamber, showing a plan view of the valve shown in Fig. 4.

The drawings show burners 1 and 2 of ordinary construction to which an air feed-.

ing chamber 3 is connected. Mixing chambers 4 are rigid with the chamber 3 and openings 5 form passages from the air feed chamber 3 to the mixing chambers l. Valves 6 are provided for regulating the amount of air which passes from the air feed chamber 8 to the mixing chambers. A gas pipe 7 is provided and tubes 8 form passages from the pipe 7 to the mixing chambers 4 and gas cocks 9 are provided for the tubes 8. An air receiving chamber or box 10 is rigid with the air feed chamber 8. This box 104s taper- Specification of Letters Patent.

ing in form, the receiving end being flared for receiving the air. The air is filtered by means of a sieve or screen 11 which is placed over the mouth or receiving end of the air receiver. In this construction, all of the air that goes to the mixing chambers 4; is screened or filtered. There will be nothing coming from the atmosphere to clog or choke the burners, and the gas is consumed without making smoke.

Figs. a and show a variation in the valves for controlling the amount of air admitted to the mixing chambers. A valve 12 is pivotally connected to the bottom of the air feed chamber 3 by a bolt 13 which projects below the bottom part of the air feed chamber and loosely through the said bottom part and a spiral spring 14 is mounted on the bolt and serves to hold the valve 12 close tothe bottom of the air feed chamber. The valve 12 has an opening 15 therein and this opening may be made to register with the passage 5 or to open any part of the passage 5. The valve 12 can be turned on the pivot bolt 13 to any position desired.

Only two burners are shown. It is apparent that any number of burners may be used and connected to the mixing chambers 4:.

Various changes may be made in the sizes and proportions of the several parts without departing from my invention.

The air filtering receiver 10 is flared at the receiving end or made larger than at the discharge into the air feed chamber 3 so that the screen 11 can never be choked. The screen 11 spreads over so much greater area than a cross-section of the discharge that there will not be suflicient air pressure to lodge fibrous material against the screen 11. The passage into the receiver will remain open for the reception of air for feeding the chamber 3.

lVhat I claim, is,

1. The combination with a series of gas burners of an air filterer comprising an air feeding chamber, a series of mixing chambers rigid therewith and having communication therewith, and connected with said series of burners, a series of valves for said mixing chambers, each valve projecting down through said air feeding chamber and adapted to open more or less the opening into each mixing chamber, a receiver for said air chamber having an enlarged outer end, and a screen closing said enlarged outer receiving end and said receiver tapering end. down to the cross section size of said air 2. The combination With a series of gas feeding chamber, and a screen covering said 10 burners of an air filterer comprising an air receiving end. 5 feeding chamber communicating With said In testimony whereof I set my hand this series of burners, a receiver connected to said 29th day of March, 1916. chamber and having a relatively large flared WILLIAM B.
